Tog'l is a construction toy made from 1967 till 1971 by Mattel to compete with Lego. They have one or two pins on each block, and every block has a built-in little door. This allows for movement of various constructions built from this block. The block's hinge is very heavy duty. Blocks were mostly red or yellow, with occasional blue, orange and green blocks.

Unfortunately for Mattel, it was only moderately successful...
